Hello all, Here's the LOAD_PATH for my desktop: /usr/local/lib/ruby/site_ruby/1.8 /usr/local/lib/ruby/site_ruby/1.8/powerpc-darwin8.10.0 /usr/local/lib/ruby/site_ruby /usr/local/lib/ruby/1.8 /usr/local/lib/ruby/1.8/powerpc-darwin8.10.0 . Here's the LOAD_PATH for my laptop: /usr/local/lib/ruby/site_ruby/1.8 /usr/local/lib/ruby/site_ruby/1.8/i686-darwin8.9.1 /usr/local/lib/ruby/site_ruby /usr/local/lib/ruby/1.8 /usr/local/lib/ruby/1.8/i686-darwin8.9.1 . Installed gem 'flacinfo-rb' and the path looks like this on both machines: /usr/local/lib/ruby/gems/1.8/gems/flacinfo-rb-0.3/flacinfo.rb (although I would have expected to find it here: /usr/local/lib/ruby/site_ruby/1.8/flacinfo.rb) On my laptop success with: irb(main):001:0> require 'flacinfo' => true On my desktop this: irb(main):001:0> require 'flacinfo' LoadError: no such file to load -- flacinfo from (irb):1:in `require' from (irb):1 If I move the gem to site_ruby on my desktop, the load succeeds. My question is why the inconsistency? If the install location is incorrect why does require work on one machine and not the other? Here's the result of the install command on both machines: Successfully installed flacinfo-rb-0.3 Installing ri documentation for flacinfo-rb-0.3... File not found: lib Is that last bit significant? Thanks for any info, Dan J.
